3. Health probe system with real authenticated API calls to Document AI, Claude/OpenAI, Supabase, and Firebase Auth
4. Alert service with email delivery, deduplication cooldown, and config-driven recipients
5. Admin-authenticated API layer with health, analytics, and alerts endpoints (404 for non-admin)
6. Frontend admin dashboard with service health grid, analytics summary, and critical alert banner
7. Tech debt cleanup: env-driven config, consolidated retention cleanup, removed hardcoded defaults
